I am trying to make a door that uses the seonsor from OpenPeripherals so I (TheEisbaer) and my friend (Eisbaer68) can enter our house.

This is what I got so far:


list={{name = "TheEisbaer"},{name = "Eisbaer68"}}
nearbyPlayers=peripheral.wrap("right").getPlayers()

for i=1,<how many players are arround> do
for j=1,2 do
if list[j]==nearbyPlayers[i][2] then
print("success!")
rs.setOutput("left",true)
sleep(2)
rs.setOuput("left",false)
else
print("failure!")
end
end
end

So how do I make that working:

How do I detect how many players are arround?
How do I make it working only for me and my friend?

Thanks in advance.

EDIT:

I tried a bit in Ideone.com with this code:


players={{uuid = "abc",name = "TheEisbaer"},{uuid= "def",name ="Eisbaer68"},{uuid= "ghj",name = "kevin"}}
list={name ="TheEisbaer",name = "Eisbaer68"}
for i=1,3 do
for j=1,2 do
  if list[j]==players[i][2] then
   print("success!")
  else
   print("failure!")
  end
  print(i,j)
end
end

And somehow it alway says success! though it should say failure! at least at some point.

The two bits of code you posted aren't really related, so I'll address them seperately

A few things to keep in mind:

Spoiler


test = { name = "hi", name = "bye" }

That gives 'test' a single entry ("bye"), since you override 'name'

You want to do this instead:


test = { "hi", "bye" }

And to get the length of a table (Also works with strings):


test = { "hi", "bye" }
print(#test) --#> 2

Now, the sensor program is a good start.

Spoiler

I actually wrote one a while ago for my own base, here is the pastebin: http://pastebin.com/JXn1eZta
It doesn't actually look for a certain player, it opens the door when ANY player is near.
It shouldn't be too hard to modify to accept a whitelist

Your code would work too, it just needs some touching up


local list = { --# The people who will trigger the door to open
  TheEisbaer = true,
  Eisbaer68 = true
}

local sensor = peripheral.wrap("right")

while true do --# Continue forever, stop with ctrl+r or ctrl+t

  local names = sensor.getPlayerNames() --# Ask the sensor for a list of the players in range

  for i=1, #names do --# Continues for the length of names

	if list[ names[i] ] then --# Checks if there is an entry in 'list' for the player name
	  print("success!")
	  rs.setOutput("left",true)
	  sleep(2)
	  rs.setOuput("left",false)
	end

  end

  sleep(2) --# Make sure to add some delay, at least a second

end

The second bit of code you posted isn't necessary for the senor code to work, but I'll try to help you with it anyway:

Spoiler

So basically, this code goes through a table to check for an entry:


players = { --# The table to check
  {uuid = "abc",name = "TheEisbaer"},
  {uuid= "def",name ="Eisbaer68"},
  {uuid= "ghj",name = "kevin"}
}

list = { --# The table of things to check for
  "TheEisbaer",
  "Eisbaer68"
}

for i=1, #list do --# Go through all the elements in 'list'

  for j=1, #players do --# Compare it to all elements in 'players'
	if list[i]==players[j]["name"] then --# players[j][(number)] doesn't work, since you used name = "name" and uuid = "uuid"
	 print("success!")
	else
	 print("failure!")
	end
	print(i..","..j)
  end

end
